Abstract

The invention discloses a hyperbolic definition demonstration and curve drawing instrument. According to the invention, hyperbolic internal rules and parameter relationships can be visually expressedthrough a demonstration process; the moving track of the moving point can be directly drawn into an image; drawing can be carried out on a raw material with a plane or a fixed plane; the instrument can be widely used as a tool for a long time; the instrument comprises a chassis, a sliding block frame beam, a base plate, a first positioning pipe, a second positioning pipe, a first straight toothedbar, a second straight toothed bar, a driving device, a painting brush and a tape ruler, and has the advantages that the operation is simple, all demonstrations, curve drawing and the like can be completed only by rocking a handle, the functions are complete, and hyperbolic curve demonstration and track curve drawing of any parameter can be completed; drawing accuracy is high, structure is compact, cost is low, and carrying is convenient; feasibility is good, and the instrument can demonstrate and draw at any angle in various occasions, and is suitable for teaching, engineering design, fixed place processing and the like.

Description

technical field [0001] The invention relates to a teaching instrument, in particular to a hyperbolic definition demonstration and curve drawing instrument. Background technique [0002] Hyperbola is the most commonly used curve, its composition and characteristics are the content that middle school students must master, and it is widely used in practice, such as engineering design, mechanical processing, clothing cutting and so on. When middle school students are studying, they start from the definition and gradually study their characteristics, often relying on teachers to draw rough hyperbola by freehand drawing or using zipper-connected brushes on a blackboard or wall chart, and students cannot feel the inner connection that forms the hyperbola. and the function of each parameter, the hyperbolic rulers currently used by engineering technicians or production workers are limited in the selection of parameters, the speed and accuracy of drawing, the degree of automation and ...
